The role definition for mid-managers of direct supervision jails was formulated by mid-manager practitioners. This role model directed a search of the literature regarding classical managerial roles and responsibilities and resulted in an analog for mid-managers of direct-supervision jails. The conception of the mid-manager is that of a starter motor, the energy system for turning the interlocking gears that symbolize mid-management processes, interventions, and functions. Job elements are mid-manager/leader, communicator, facilitator, coach, trainer, mediator/negotiator, planner, problemsolver, organizer, decisionmaker, delegator/director, controller/auditor, evaluator, and researcher. The process of the training design involves eight interdependent steps which carry the practitioner through a systematic study of theory pertaining to mid-management of direct-supervision jails and indepth exploration of managerial processes, interventions, and functions experimentally lodged in the context of Grand Junction, USA, a direct-supervision jail simulation program.
